RESILIENT TIRE.

Original application filed January 19, 1911, Serial No. 603,552. Dividedand this application filed December 15, 1917.

To all whom it may concern:

Be it known that I, JOSEPH S. WILLIAMS, a citizen of the United States,residing at Riverton, inthe county of Burlington, State of New Jersey,have invented a new and useful Resilient Tire, of which the following isa specification.

My present invention is a division of my co-pending application, SerialNo. 603,552, filed January 19th, 1911 and patented December 18, 1917,No. 1,2503%.

The object of my invention is to provide a tire which can be applied tothe present rim equipments which will be free from the complicatedstrains to which an ordinary type of circular tire is subjected inservice due to the flattening of the arch in transverse section inproportion to the chord line of the annular arch formation of'the tire.

It is a further object of this invention to provide the spanningportions of the flat tened arch in transverse section with curva turesin the sides of the spans of about ninety degrees outwardly of the majortransverse axis of the tire, so that such will provide flexing supportstangential to the annular and transverse spanning portions crossing theplanes of the tire between such curvatures.

It is a further object of this invention to employ, position and combineflexible tension with vulcanized rubber annularly and transversely inthe flattened arch formation to secure the requisite standards ofstability to restrain undue circumferential and lat eral elongation anddeformation of the flattened arch and the portions of the tire inwardlyof the major axis when the tire is on wheel equipment and subjected topressure from within by any suitable means to provide load supportingcapacities therein.

Other objects and advantages of my invention will hereinafter appear inthe detailed description.

For the purpose of illustrating my invention, I hav shown in theaccompanying drawings a typical embodiment of it which is at presentpreferred by me, since this embodiment will give in practicesatisfactory and reliable results, although it is to be understood thatthe various instrumentalities of which my invention.consists can bevariously arranged and organized and that my invention is not limited tothe precise arrangement and organization of these in- Specification ofLetters Patent.

strumentalities as herein shown and described.

In the drawing, I have shown, in transverse section, a tire embodying myinvention. w

Referring to the drawing:

1 designates a tire embodying my invention and consisting of an outershoe or casing 2 and a fluid tight tube 3. The shoe 2 consists ofmultiple layers 4.- of rubber and tensile material, for example, fabric,vulcanized together and disposed in a novel manner. Inwardly of themajor axis of the tire in cross section, the shoe is disposed in archformationfrom the major axis to the beads 5. ()utwardly of the majoraxis the shoe is disposed in flattened arch formation; The curvature 6at the sides outwardly of the major axis are, as shown, at substantiallyninety degrees and the connecting portion 7 between such curvatures isdisposed substantially parallel with the major axis. The shoe is alsoprovided with one or more layers 8 of tension portions extendingcircumferentially and preferably concentric with the layers 4.

The layers 8 are formed of anv desired number of layers of vulcanizedrubherand tensile material. 9 designates the tread, the contact surfaceof which lies within a circle formed by a radius of one-half the majoraxis of the tire in cross section. The contact surface of the tread ispreferably flattened, as indicated at 10. If desired, an annularflexible reinforcement 11 of a material of a high standardof tensility,such as nickel, carbon or vanadium steel may be disposed in the shoesubstantially parallel with the major axis. This does not prevent theflexing of the shoe and serves to resist internal pressure from withinthe tire and to resist puncture of the tire from without. This member 11is preferably incased in and combined with tough or soft rubber 12 of ahigh standard of tensility which is combined with fabric. The inner tube3 is formed of fabric and rubber vulcanized together with the fabricextending annularly and transversely and conforming in contour to theinner periphery of the shoe. The tube is provided with any desired orconventional type of valve mechanism (not shown) for introducing intothe tube fluid under pressure or any other desired type of mobilematerial or fillin -nates the local action which takes place It will beseen that inwardly of the major axis in cross section, the tire conformsin contour to an ordinary tube while out- Wardly of such major axis itis in flattened arch formation with tensile material to restrictCircumferential elongation and with tensile material in flattenedformation throughout the width of the tread contacting' surface whichtends to restrict lateral elongation of the tire at such portion. Thebeads 5 are shown as of the conventional clencher type but any otherform of terminals may be employed to coact with the type of rimmechanism with which the tire is to be used.

The tensile material which'provides the lateral tension extends aroundthe sides to the beads or terminals and providesthe requisite tensilestrength to resist internal pressure and maintain theflattenedarchformation and proper 'coaction with the terminals and inner seatingportions.

My present invention has many advantages over the ordinary circular typeof tire. The flattened arch formation elimiunder load compression in theordinary pneumatic'type of tire, and gives a larger area of resillentsupportfor the inner. portion of the tread. i

It also provides for using a much greater depth of tread than ispracticable in the metal member contributing under operative ordinarycircular tlre and maintaining the tread surface mainly or entirelywithin a circle formed by a radius of one-half the diameter of the tire.

lit will now be apparent that I have de- 7 vised a novel and usefulresilient tire which embodies the features of advantage enumerated asdesirable in the statement of the invention and the above description,and while I have, in the present instance, shown and described a typicalembodiment of it which will give in practice satisfactory and reliableresults, it is to be understood that this embodiment is susceptibleofmodification in various particulars without de parting from the spiritor scope of the invention or sacrificing any Having thus described myinvention, what I claim as new and desire to secure by Letters Patent,is

l. A tire having a tension belt in circular formation inwardly ofthe'maj or transverse axis of the tire in cross section and in fiatofits advantages.

tened arch formation outwardly of said axis, said tension belt havingcombined in its flattened arch formation annular reinforcements oftensile material to limit under working conditions of internal pressureand load within definite ranges the inward and outward'movements of theflattened arch formation and the lateral movements of the side walls ofthe tension belt, and a tread outwardly of said tension belt.

2. A tire having a tension belt in circular formation inwardly of themajor transverse axis of the tire in cross section and in flattened archformation outwardly of such axis and in proximity to it, said tensionbelt having combined in its flattened arch formation annularly andtransversely disposed reinforcements of flexible tensile materialcontributing underoperative conditions of load and internal pressure torestrain circumferential and transverse elongation of such flattenedarch formation, a tread outwardly of the tension belt and means withinsaid belt to maintain it in tension when under load.

3. A tire having a tension belt in circular formation inwardly of themajor transverse axis of'the tire in cross section and in flattened archformation outwardly of such axis and in proximity to it, said tensionbelt having combined in its flattened arch formation an annularly andtransversely disposed conditions of load and internal pressure torestrain circumferential and elongation of such flattened archformation, a tread outwardly of thetension belt, and

means within said belt to maintain it in tension when under load.

LA tire having a tension belt in circular formation inwardly of themajor transverse combination with said flattened arch forma tion, and atread encircling the flattened arch formation.
